Rams i have learned to source f1’s directly before they enter the lfs tanks. Skip the Thailand bred rams they have at most places.
I dont know if its inbreeding, in tank fighting etc but ram tanks seem to always have fw velvet. Ime if a ram gets ill before settled they dont make it. Also freshwater velvet unlike fw ich does not get cured with salt and temperature treatment.
Bolivians keep your tank at normal tropical temperatures mines at 78. Blue rams a touch higher into the 80’s.
These are hard to pair fish. If buying multiples 2 one male per 20 gallons. If theres breeding pair, they will defend 3 feet of tank from other rams. To get a pair males are picky need to buy like 1 male and 5 females will pick one lol. Not as easy to sex as blue rams but still can do visually.
My experience with them anyway.
